Comparison of Characteristics Between ICS-Treated COPD Patients and ICS-Treated COPD Patients with Concomitant Asthma: A Study in Primary Care

Distribution of health problems at the general outpatients' clinic of the University of Hong Kong-Shenzhen Hospital: A cross-sectional study

Objective

The study aimed to understand the distribution of health problems of a general practice clinic to provide guidance on how to develop primary care in Shenzhen, China.

Study design

This is a cross-sectional study.

Methods

Patients' sociodemographic data and diagnoses were recorded from the electronic medical record system of the University of Hong Kong-Shenzhen Hospital from Jan 2014 to Dec 2020 and coded using the International Classification of Primary Care-2. Descriptive statistics were used to describe the distribution of health problems.

Results

A total of 368,167 health problems were recorded. Respiratory, digestive, musculoskeletal, general, and cardiovascular were the top five categories, which accounted for 67.71% of the total in this study. Acute upper respiratory tract infection (AURTI) was the most common health problem (6.67%). Chronic diseases, including hypertension and diabetes mellitus, accounted for about 7% of all health problems. The proportion of cardiovascular problems increased significantly with age (r = 0.96, P < 0.05). The proportion of consultations for mental health problems was low in all age groups.

Conclusions

The results represent an understanding of the common health problems of patients in Shenzhen city, which can provide a reference for preventing diseases and developing primary care.

Characteristics of COPD Patients Prescribed ICS Managed in General Practice vs. Secondary Care

Inhaled corticosteroids (ICS) for COPD have been much debated. Our aim was to investigate characteristics of ICS prescribed COPD patients managed only in general practice compared to those also managed in secondary care. Participating general practitioners recruited patients with COPD (ICPC 2nd ed. code R95) currently prescribed ICS (ACT code R03AK and R03BA). Data on demographics, comorbidities, smoking habits, spirometry, dyspnea score and exacerbation history were retrieved from medical records. Logistic regression analysis was applied to detect predictors associated with management in secondary care. 2,279 COPD patients (45% males and mean age 71 years) were recruited in primary care. Compared to patients managed in primary care only (n = 1,179), patients also managed in secondary care (n = 560) were younger (p = 0.013), had lower BMI, more life-time tobacco exposure (p = 0.03), more exacerbations (p < 0.001) and hospitalizations (p < 0.001) and lower FEV₁/FVC-ratio (0.59 versus 0.52, respectively). Compared to patients managed in only primary care, logistic regression analysis revealed that management also in secondary care was associated to MRC-score ≥3 (OR 2.70; 95% CI 1.50-4.86; p = 0.001), FEV₁%pred (OR 0.98; 95% CI 0.95 to 0.99; p = 0.036), and systemic corticosteroids for COPD exacerbation (OR 1.44; 95% CI 1.10-1.89; p = 0.008). In COPD patients prescribed ICS recruited in primary care, patients also managed in secondary care had more respiratory symptoms, lower lung function and exacerbations treated with systemic corticosteroids indicating that the most severe COPD patients, in general, are referred for specialist care.
